Method for producing plasma display panel

Abstract

An aggregated particle paste containing aggregated particles, each composed of a plurality of aggregated crystal particles made of magnesium oxide, and a solvent is prepared. A crystal particle paste containing crystal particles having a cubic shape, made of magnesium oxide, and a solvent is prepared. Thereafter, by mixing the aggregated particle paste and the crystal particle paste with each other, a mixed crystal particle paste is prepared. Then, by applying the mixed crystal particle paste to the base layer, a mixed crystal particle paste film is formed thereon. Thereafter, by drying the mixed crystal particle paste film, the aggregated particles and crystal particles are dispersed over the entire surface of the base layer.
